TS ISO 6790

TS ISO 6790 defines graphical symbols used on fire protection plans. The standard provides a common visual language for architectural and engineering drawings so that fire protection provisions, fire-fighting equipment, and escape routes can be shown consistently across design, renovation, and fire certification workflows.

What the symbols do on a plan

Fire protection plans do more than locate equipment; they communicate how a building is organised for fire safety. Symbols help identify items such as extinguishers, alarm points, hose systems, escape directions, and related protective features at a glance. By using standardised graphics, drawings become easier to read and less dependent on lengthy written notes.

Technical context and use cases

• The symbols are intended for the representation of fire protection and fire-fighting equipment on drawings.
• They support clear depiction of means of escape and related safety arrangements on plans.
• The application area covers architecture, engineering, building construction, and allied design fields.
• The standard serves projects prepared for design, renovation, and fire certification purposes.
• It addresses the specification of graphical symbols for fire protection plans.

In general technical practice, symbol standardisation creates a shared visual vocabulary for project teams, inspectors, and emergency-planning professionals. That improves consistency across drawings and helps different parties interpret the same plan more reliably, while actual use still depends on the drawing discipline and applicable local rules.
